two dimensional jet in cross-flow -- CFD Online Discussion Forums

Piet Guest Posts: n/a	Dear CFD-users, I am modelling a two dimensional jet in cross-flow configuration. Properties of water are used and it is modelled with the latest version of COMSOL Multyphisics. The velocity ratio Vjet/Vcf is 0.75. The full Navier-Stokes equation has to be solved. I have problems with the outflow boundary condition. I use a pressure = 0 condition. Also when I decrease the inflow velocity, problems appear. Does anybody have an idea how to solve the problem? Thanks for the comments in advance! Regards, Piet
